Medical officials in the Palestinian territory say many of those killed were civilians. But because of Israel's restrictive media access to Gaza, those figures are hard to confirm.

Israel says it is not targeting civilians, and it has accused Hamas gunmen of launching rockets from populated areas.

Thirteen Israelis have been killed, including 10 soldiers, along with three civilians hit by rocket fire.

Gaza medical officials say about 850 Palestinians have died in the Gaza Strip since Israel's military offensive began December 27. Officials estimate that half of those killed have been civilians.

Israeli Prime Minister Ehud Olmert said in his weekly Cabinet meeting today that the military is fulfilling its goals, but will continue the offensive against Hamas until militant rocket attacks on southern Israel stop.

Separately, an Israeli military spokesman said army reservists, held back until now, are being deployed to Gaza.

On Saturday, Israel's military issued a warning to residents of the Gaza Strip that it intends to intensify its offensive against Palestinian militants. Aircraft dropped leaflets warning that the Israeli army will continue attacking tunnels, weapons caches and terrorists with increasing force throughout the Gaza Strip.

Exiled Hamas leader Khaled Meshaal, speaking in Damascus Saturday, accused Israel of perpetrating a "holocaust" in the Gaza Strip. He said the Israeli offensive in Gaza has eliminated the possibility of lasting peace between Israel and the Arab world.
